Study Notes

Part I - The Challenges

Information and intellectual capital are more valuable to a company than physical assets
Most organizations believe their information systems are secure, but this is not the reality
Information security needs a layered approach to protecting many different forms of information
Threats to information involve various forms including theft, solicitation, and hostile interception,
Espionage by foreign governments happens on a large scale to gain economic advantage; this involves front companies, joint ventures, or suppliers to the target.
Government-level espionage isn't limited to traditional adversaries
Industrial espionage happens between various countries and companies
Companies and employees can steal information, leading to many risks to organizations

Competitive Intelligence

Espionage is often confused with competitive intelligence (CI)
CI examines the strengths and weaknesses of competitors
It is challenging to draw a clear line between legitimate CI and illegally acquiring intellectual property.

Cyber Sabotage

Denying access to data is damaging to organizations, and in some cases, more so than theft
46% of UK companies surveyed experienced a cyber security breach in 2017
Temporary loss of network/file access and corrupted systems are the most common outcomes of cyberattacks
The WannaCry ransomware attack encrypted machines and demanded ransom from over 230,000 computers.

The CIA triad

Confidentiality, Integrity, and Availability (CIA) are fundamental to information security
Confidentiality: Restricted access to information for only authorized personnel and with need for the information
Integrity: Guaranteeing that information isn't altered, modified or manipulated in unauthorised ways
Availability: Ensuring the continued, uninterrupted accessibility of information to authorized users.

The Threat Tempo

The threat tempo is increasing due to the rapid evolution of technology
New technologies and cyberattack methods rapidly increase
The security industry must constantly adapt to these new challenges.

Specific Idiosyncrasies of Information as an Asset

Information can take various forms, from spoken word to computer data
Intangible information is hard to effectively protect
Difficulty in accounting for all information assets.

The Information Lifecycle

Information takes different forms throughout its lifecycle
Information can be converted from handwriting to digital formats and stored in various ways
Many parties may access and share information, raising concerns for security

The Adversaries

Outsiders, malicious insiders, inadvertent disclosure, and collusion with outsiders are all types of adversaries, although these categories may be too simplistic to capture the full adversary landscape
Employees: Staff are frequently the target of espionage attempts
Competitors: Companies spy on one another using many methods
Business Partners: Businesses often trust their partners, creating an opportunity for threats arising from their employees
Foreign Governments: Foreign governments frequently target competitor companies for economic espionage, often targeting employees.
Journalists: News organizations and journalists can pose threats when sensitive information is leaked in pursuit of their stories.
Activists: Individuals opposed to certain entities are a potential source of threats, especially those active in cyberspace
Criminals: Criminals may want the data for identity theft or other criminal enterprises

Insider Threat

Insiders are particularly risky and pose a difficult threat to mitigate.
Employees, former employees, contractors and business partners can be malicious insiders
The loss or modification of information by an insider can have a large impact on organizations
A common motivation for insider threats is the intent to support competitors or outside entities when moving to a new job opportunity
The risk of insider threats is amplified due to current business requirements for mobility and remote technology support

Basic Protection Principles

Basic protection principles can be summarized with TRAPP: Technology, Response, Awareness, Procedures and Programmes, Physical security
Information classification can help people determine what information is sensitive
Some information systems are more important to organizations than others
Procedures and programming strategies are important elements of protecting information and systems
The effectiveness of many security measures depends on a strong company culture

Operational Security (OpSec)

OpSec protects non-sensitive information that can still reveal an organization's operations, capabilities intentions, and goals;
OpSec can include basic measures such as clear desk policies, limiting who has access to certain information,
Careful physical security of equipment and personnel is important
OpSec is crucial in managing risks to employees who are overseas, especially when they have access to sensitive information.

Incident Response and Investigations

The risk of an information breach can never be fully eliminated
It can be mitigated if a well-designed incident response plan is in place to identify, respond to, and follow up on an incident effectively
The ideal response plan should include roles and responsibilities, risk assessment analysis, procedures for reporting incidents, plans for handling different scenarios, and scheduled training and exercises for improving response skills.
